I’m watching this arborist on YouTube and they have a truck with a bucket on an arm so they can reach heights without climbing. On/after a rainy day the bucket will accumulate water and they mentioned they can’t drill a hole to drain because it will compromise the grounding.
My understanding of grounding/electricity doesn’t explain this. Can someone help me understand why this would make a difference?
Edit: I get it, I/he should have said “electrical isolation” instead of “grounding”. Either way, a hole allowing a stream of dirty water seems to be the answer here. Thanks 🙂

I’d need more details on the construction of their bucket and how it’s grounded. Assuming there’s some kind of earthing cable running up the armature into the floor of their bucket, then yes, just drilling a large hole through the plate (and into the cables) could create an issue. That area they damaged would have different resistance, under load it could heat up and melt.
That said, an engineer with details of their bucket could design a proper drainage system. Even if you can’t drill a hole, you can use a subfloor, pump, and siphon to move water out of the bucket.
